Title: Method for processing semiconductor wafer immediately after polishing
Inventor: HENNHOEFER HEINRICH
IPC: H01L21/306
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To prevent the number of luminous point defect from increasing during storage by bringing a semiconductor wafer into contact with an aqueous processing agent immediately after polishing and oxidizing the polished surface of a water through action of the aqueous processing agent. SOLUTION: A semiconductor wafer is coated, on the polished surface thereof, with a thin inactive oxide through action of a processing agent, i.e., an aqueous oxidative alkaline solution. The aqueous processing agent is added with hydrogen peroxide (H2 O2 ) and an alkaline component as an oxidizing agent. Since the wafer is brought into contact with the aqueous processing agent when the wafer is still set on a polishing plate, oxidation takes place in a polishing machine of an unload station of wafer coupled therewith. After finishing the oxidation process, the processing agent is washed away from the wafer using deionized water. According to the method, the number of luminous point detects(LPDs) is prevented from increasing immediately after polishing.

Title: Magnetic head support device
Inventor: TANAKA YOSHITO
IPC: G11B21/20
Filed: 1986-02-21
Abstract: PURPOSE:To prevent a magnetic head from being tilted in front direction at disk running by cancelling a moment produced in a magnetic head due to friction attended with the running of disk by a reverse moment due to the weight exerted from a pivot. CONSTITUTION:The position of the support axis X-Y along the disk radial direction among the support axes along the disk circumferential direction and the disk radial direction of gimbals 6, 7 supporting magnetic heads 4, 5 is deviated this side of the running direction (arrow A) of a flexible disk 11 from the position of pressing point of pivots 8, 9.
